  1. Kamal bought a house in Sushant city, whose sale price was Rs. 8 lakh. He availed 20% discount as an early bird offer and then 10% discount due to cash payment. After that he spent 10% of the cost price in interior decoration and lawn of the house. At what price should be sell the house to earn a profit of 25% ?
    1. Rs. 9 lakh
    2. Rs. 7.99 lakh
    3. Rs. 7.92 lakh
    4. none of these
  1. Correct Option: C

    Assume market price (MP) = Rs. 100
    After 20% discount price = 100 - 20% = Rs. 80
    After cash discount of 10% price = 80 - 10% = Rs. 72
    Price after 10% spend on interior decoration = 72 + 10% = Rs. 79.2

    So the cost price (CP) = Rs. 79.2
    Selling price after 25 % profit = CP + 25%
    = 79.2 + 25% of 79.2
    = 1.25 x 79.2
    = 99

    When initial market price is 100 rupees the selling price is 99.
    So for initial market price 8 Lakh the selling price = 8000000 x ( 99 / 100 )
    = 7,92,000
